Abstract
Active movement-assistive devices aim to increase the quality of life for
patients with neuromusculoskeletal disorders. This technology requires interaction
between the user and the device through a control interface that detects the user’s
movement intention. Researchers have explored a wide variety of invasive and
non-invasive control interfaces. To summarize the wide spectrum of strategies, this
paper presents a comprehensive review focused on non-invasive control interfaces
used to operate active movement-assistive devices. A novel systematic classification
method is proposed to categorize the control interfaces based on: (I) the source of
the physiological signal, (II) the physiological phenomena responsible for
generating the signal, and (III) the sensors used to measure the physiological
signal. The proposed classification method can successfully categorize all the
existing control interfaces providing a comprehensive overview of the state of the
art. Each sensing modality is briefly described in the body of the paper following
the same structure used in the classification method. Furthermore, we discuss
several design considerations, challenges, and future directions of non-invasive
control interfaces for active movement-assistive devices.
